Activating license for Encoder 4 input & Wheatstone Bridge Sensor Interface apps not working

Hi!

I require your help regarding a problem I’m encountering.

Description:
Both apps (Phidget Encoder 4 input & Phidget Wheatstone Bridge Sensor Interface) keep failing at the activation --> “Check your internet connection or firewall.”

Hardware concerned:

Software concerned:
Phidget Encoder 4 input
Phidget Wheatstone Bridge Sensor Interface

Troubleshooting steps already taken:
I have tried multiple different networks (2 Smartphone Hotspots, 3 different private networks) but the error-massage keeps reappearing.
Different users, both local and domain, with administrator-rights have been tested, none have worked.
No additional anti-virus software is installed and the standard Windows-Defender has been deactivated as well.
GPOs have all been deactivated.
And yes, I have a working internet connection.

I have also tried changing one number in the key to a wrong one - then I got a error massage “The code you entered is not valid.”, so it does seem to check / work so far at least.

Additional information:
Client is joined to a local on premise domain.
OS: Windows 10 Enterprise 1909 (18363.418)

@Mosca_Brandt Welcome to the RobotShop Community. We will provide you with a free RB-DSP-06 which you can use to run the apps rather than the .exe. We will transfer this ticker to our RMA department who will then provide you with an order for $0 total. Please install the software using the license number which will be provided, and then run the .fbs which is part of each app via the software.
